[NCLUG] Lost mail due to graylisting!

[Stephen Warren]

Yikes - a few days ago, I purchased a ticket on americawest.com and 
requested an email copy of the itinerary. My maillog shows that their 
mailserver did contact me, and got graylisted, but never attempted any 
retries in 3 days - I guess it's given up. The other person the 
notification was sent to got it fine, luckily.

That's a bit of a bummer - it's the first (non-spam!) email I've lost 
due to graylisting. Guess I have to whitelist their domain or something.
